I have always dyed my hair red but as it's going grey the colour isn't covering it. I have been wary of henna because of hassle, mess and looking like a 90s hippie concerns.
If I try it a) will it cover grey hair properly b) will it fade quickly c) will it ruin my hair for chemical dyes if I don't like it and d) is it a horrible faff? Oh and e) will it look like a 90s art teacher?
